can they be reused by adding more water once the dry out, or i have to buy new ones once in a while?

Yes, distilled water or "cigar juice" can be added to recharge these. There are lines on the tube marking when to recharge and the max fill line.

Just add more water to the fill line. The gel inside lasts a really long time.

These can be refilled with water. Distilled would be best. You can also use Xikar or Cigar Caddy use everytime solutions.

Add water. Shake it up. I've only done it once. I have a disc humidifier now.

I don't know for sure, however as long as they are kept in a cool dry place and the seals are still in place, I don't see them drying up. Once installed, they need to be used, if you remove them, you must reseal them. But watch out for your ink jets getting clogged not having any ink to keep them wet.

yes you can. keep them in the ziplock bag. Drop a little water on them and they are sticky again.

I'm sure you could use them, but the paint and constant use of water may make them hard to use over-and-over.

As I understand that you can reuse till they get hard. I've reused mine over 6 months and are still good and there still moist but when they get hard they say to replace. But for the best answer go to there website and check faq.

That last about the same but are cheaper. You can also reuse them by rising them out the a hose with the spray attachment on it

Depends on size of tank and amount of fish. But common rule is rinse them with non chlorine water once every two weeks and change 15 percent of the water. Yes some are reusable, but leave one old one everytime

I don't think you can re-use the disposable cups. It would be difficult to get the lid off to refill them once they are put on, plus once they are punctured by the machine I don't think they would be any good. I wouldn't try it myself. If you did you would have to get extra filters and I haven't seen them sold without the cups and you can't use them without the filter.

I haven't needed to replace them yet but I have rinsed them under a hard stream from the fawcet then air dried them til really dry & that`s worked really well. When needed, I plan on buying them directly from the manufacturer.

Most often I have not been able to reuse them. There have been a couple of occasions that I have been able to use them twice.

They can be reused short term. After being used once they slowly begin to breakdown on the inside. I used them for my basement door during hurricane Sandy and they were able to be used again a few weeks later.

yes they are reusable and refillable. I have not had any leakage problem so far.

No, they cannot really be reused. You could try spraying them with water I guess to experiment but they are not made to be reused. I really think they were worth getting and did last a few months in the original jar of material I had them in, but they eventually dried out and became hard. I do live in a really dry climate thought, so take that into consideration as well.

No, just reseal the bag so they don't dry out. I have had some that were good after several months.

You can use them anywhere but water must be dumped regularly and more damp rid or the likes refilled.

You can reuse them. It's difficult to get them off but you can use a dull knife to get it started.

It depends. If the package says "Use only once" then you dispose them after one use, if it says "Reusable," then you can wash and reuse them. HIH.
